Portable electronic device

Abstract

A portable electronic device (wrist device) includes: a case (top case and bottom case); a display unit accommodated in the case; a cover plate closing an opening of the case; and a moisture absorbing member disposed along an outer edge of the display unit between the cover plate and the display unit.

What is claimed is: 
     
       1. A portable electronic device comprising:
 a case including an opening; 
 a bezel provided outside the opening of the case; 
 a display unit accommodated in the opening of the case; 
 a circuit board provided below the display unit and accommodated in the opening of the case; 
 a cover plate closing the opening of the case; and 
 a moisture absorbing member that is:
 (i) disposed along an outer edge of the display unit such that an outer edge of the moisture absorbing member is further outward than the outer edge of the display unit, 
 (ii) disposed between the cover plate and the display unit and spaced apart from the cover plate, and 
 (iii) disposed below the bezel such that the outer edge of the moisture absorbing member contacts the case without contacting the bezel. 
 
 
     
     
       2. The portable electronic device according to  claim 1 , wherein
 the moisture absorbing member has a ring shape. 
 
     
     
       3. The portable electronic device according to  claim 1 , wherein
 the moisture absorbing member includes a display of at least one of a character, a symbol, a scale, and a pattern on a surface on a cover plate side. 
 
     
     
       4. The portable electronic device according to  claim 3 , wherein
 the moisture absorbing member includes a base layer on a front surface of the moisture absorbing member on the cover plate side; and 
 the display is located on a front surface of the base layer on the cover plate side. 
 
     
     
       5. The portable electronic device according to  claim 3 , wherein
 at least one of the display and a base layer is formed by an inkjet method. 
 
     
     
       6. The portable electronic device according to  claim 1 , further comprising:
 a plate having a ring shape disposed along the outer edge of the display unit between the cover plate and the display unit, wherein 
 the moisture absorbing member is located on a display unit side of the plate. 
 
     
     
       7. The portable electronic device according to  claim 6 , wherein
 the moisture absorbing member is disposed so as to overlap the plate in a plan view. 
 
     
     
       8. The portable electronic device according to  claim 6 , wherein
 the plate has a light transmissive property. 
 
     
     
       9. The portable electronic device according to  claim 8 , wherein
 a display of at least one of a character, a symbol, a scale, and a pattern is located on a surface of the plate on the display unit side. 
 
     
     
       10. The portable electronic device according to  claim 9 , wherein
 a base layer is printed on an entire surface of the plate on the display unit side so as to cover the display. 
 
     
     
       11. The portable electronic device according to  claim 6 , wherein
 the plate is made of a resin. 
 
     
     
       12. The portable electronic device according to  claim 1 , wherein
 the moisture absorbing member is disposed directly on a top surface of the display unit. 
 
     
     
       13. A portable electronic device comprising:
 a case having an opening; 
 a bezel provided outside the opening of the case; 
 a display unit accommodated in the opening of the case; 
 a circuit board provided below the display unit and accommodated in the opening of the case; 
 a transparent cover closing the opening of the case; 
 a moisture absorbing member that is:
 (i) disposed along an outer edge of the display unit such that an outer edge of the moisture absorbing member is further outward than the outer edge of the display unit, 
 (ii) disposed between the transparent cover and the display unit and spaced apart from the transparent cover, and 
 (iii) disposed below the bezel such that the outer edge of the moisture absorbing member contacts the case without contacting the bezel; and 
 
 a plate disposed between the transparent cover and the moisture absorbing member. 
 
     
     
       14. The portable electronic device according to  claim 13 , wherein
 the moisture absorbing member and the plate are ring shaped. 
 
     
     
       15. The portable electronic device according to  claim 13 , wherein
 the moisture absorbing member is disposed directly on a top surface of the display unit.
